movens- Hello and Welcome to G-Nutz2!Would anyone know how I would go about wiring a set of Seymour Duncan Sh2n and Sh4 JB to this switching setup It is simply a matter of translating the wire colors from PRS colors to Seymour Duncan colors. And, from looking at the PRS diagram, it appears their wire colors are the same as SD's, so this should be easy, no translation required . . .but . . . Two caveats. when I say "it appears they are the same colors" what I mean is that the PRS diagram leads me to believe that, just like SD, one coil is black/white and the other coil is red/green. But we don't know, without more information, whether Duncan's North coil is the same as on the PRS, ditto for the south coil. This wouldn't matter except for the coil splitting, we want to be sure we are splitting to the appropriate coil for hum-cancelling, and also (if it matters to you), whether it is the screw or slug coil that is being split. To know that will require more info on the PRS pickups (a quick websearch I did was unenlightening, and PRS colors/polarities are not listed in our reference charts.) Also note that the PRS diagram shows the bridge pickup being wired "inside out" from the neck (or the neck is "inside out" from the bridge, either way). If you look at the PRS diagram, see how the red and green wires swap positions, as do the black/white wires, if you examine the bridge pickup wiring versus the neck pickup? This is done so that, when both pickups are split to single coil, the combination will be hum-cancelling. You will want to do so with the SD pickups as well. This too should translate directly from PRS to SD colors, but we won't know North versus South coils. It may not matter for hum-cancelling purposes so long as the split coils are opposite, one North paired with one South. It only matters which is which if you care whether it is inside coils being split versus outside coils, or screw coils versus slug coils (if the SD HBs even have screw/slug coils, I don't know their models offhand). So, you should be good to go with the existing diagram, unless it matters to you which coils are being split. |

Great, thank you. It will be working with splits and mix of split and full HB just fine? Yes it should be fine. So assuming its on a push pull, pushed in , no difference. Pulled out, you can try mixing the single coils out of phase, or humbucking, or one of each. If you operate this switch but only select one pickup, then it will likely sound no different, The differences come in the combo settings. There's other ways to do phase switching, which include differences in which singles are used which sometimes get better hum cancelling of two out of phase singles. But this should be fine and it doesnt disturb anything clever that PRS are doing there, so I think its the best option to try. |

Perfect. Thank you to both of you gentleman. I shall report in no longer than a week how it turned out

Ive got just one uncertainty (apart from 'the meaning of life' and 'how many roads should a man walk down?" etc) On nerds diagrams, the coils splits both use the coil with black and white wires, but they are reversed between the two pickups. This suggest they have some magnetic flippage happening that may not translate to SD pickups. Definitely possible to make the sub though, just need to proceed carefully with some test or confirmation to get it right. |

Yes on regular CU24 I flipped the neck magnet and that worked
It’s the coil tap mini toggles I’m worried on.
From what I gather this is what the wiring is
The Duncan’s have
black north start
White north finish
Red south finish
Green south start
Bare
Where the bridge of the PRS 85/15 has
Red screw start
White slug tap
Green slug finish
Black coil tap
Bare
So would that still mean one to one on the color match?
And thank you for the warm welcome

I think JohnH is right, best to do some testing. "Coil tap" is inaccurate (and confusing) terminology, no coils are being "tapped" here. We're just splitting one complete coil off from a pair of coils. But I ttok your meaning. The bridge pickup is wired "inside out" (I'm guessing at that, could be the other way around . . .), so let's compare the neck colors to SD. As per the diagram, the neck's black wire is connected to output. We don't know what North vs. South is for this pickup yet, but we'll assume this is the Black/white coil's "start", same as SD's. That makes sense as per the diagram. But for the second coil, the SD pickup would have the white and red wires joined together to make the seires junction of the two coils. For the PRS (at the neck), it looks like the red is the ground connection and the white and green join for the series HB. So, now I'm not so sure. You will notice also a number of assumptions in the above, the falsity of any of those potentially throwing a wrench at things. SO, as John suggested, probably best to do some testing first. The other option is to trust to luck and be prepared to have to go in again to swap some connections around. For testing, a toy compass or a magnet with known poles and a multimeter will be needed. In the alternative, a computer with a soundcard that you have the interface to plug your guitar into, and the ability to run a audio-processing program like Reaper. If you have those items, we can walk you through it. |

It’s the “Multi Tap” coil tap phrasing that throws me off. I guess I will have to start testing with a a volt meter to figure out what is what. |

I've been looking for some nice clear info on PRS pickup wires, but im finding different arrangements, not the same as on this thread. Here's one with black and white as main outputs, and a red wire, or two: Yeah, that's what I was finding, too. It looks like most PRS HBs are 3-wire, with a single red wire acting as the series junction. These "Custom 24" models seem to be the exception, and use 4-wire HBs, but as JohnH noted, it looks like some magnet-flipping may have been done. And I couldn't find any clear explication of the wire colors vis a vis polarity. |

Is there a way I can test it?

nerd-
You don't really need to test anything, since you are keeping the stock pickups. It is the fact that movens wants to swap in SD pups that have JohnH and I recommending the testing.
In your case, any testing would really just be for your own curiousity's sake. If you have a toy compass or a magnet, you can check to see if PRS has indeed swapped the magnets around, as we have speculated was done.
If both screw coils show "north" on the compass, or if both are either attracted or repelled by the same pole of the magnet, then the coils are the same and no magnet-swapping has been done. (I put the word "north" in quotes because there is no guarantee that what PRS calls "North" is the same as what SD (or any other mfr.) would call "North".)
If the screw coil from the bridge pickup is the opposite of the screw coil from the neck pickup, then the magnets were switched, North for South, as between the Bridge and neck pickup coils.
If that is the case, the next logical question would be: "Why would a manufacturere do that?" The answer is for coil splitting- if both pickups are the same, then when the coils are split, you would need to split to one screw and one slug coil in order for the N + B coil-cut setting to be hum-cancelling. But by flipping one of the 2 magnets, then PRS could have the split be both screw coils (so the poles can be adjusted) and still be hum-cancelling.

Hi there. Just to let you know I got the pots and rest of the parts are on order. Seems like Mouser has some issues with processing orders so I'm not entirely sure when I will be able to do some progress. I was given Luxe Bumblebee 15nF cap some years ago that I'm thinking to use it here. Not expecting mojo tone but free cap is a... free cap. Will get back to yall ASAP

Just wanted to confirm the wiring works. Not sure if its worth the hassle, though
Thank you all for help with it
